Can't mount ipod ( hfsplus )

Built cfls on amd duo 64bit mostly everything is fine but I can't mount my ipod from command line I get this:

Code:

mount: wrong fs type, bad option, bad superblock on /dev/sdh2,

       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try

       dmesg | tail or so

and the results from dmesg | tail:

Code:

[ 1021.717257] sd 8:0:0:0: [sdh] Assuming drive cache: write through

[ 1021.717262] sdh: detected capacity change from 0 to 159840301056

[ 1022.214556] sd 8:0:0:0: [sdh] Bad block number requested

[ 1022.214581] hfs: unable to find HFS+ superblock

Or this after trying to manually mount:

Code:

[ 1140.949583] sd 8:0:0:0: [sdh] Bad block number requested

[ 1140.949615] hfs: unable to find HFS+ superblock

I have hfs+ enabled in the kernel and also support for apple partitions like so
CONFIG_HFS_FS=y
CONFIG_HFSPLUS_FS=y
...
CONFIG_MAC_PARTITION=y

HELP!

P.S.
The ipod mounts fine on slackware,parted magic and has been disk checked on my imac.

I was curious and did a little search and came up with this: http://en.gentoo-wiki.com/wiki/Hfsplus

The kernel options and disabling journalling parts might be of interest to you. I'm guessing you don't have all the relevant kernel options enabled.

already seen this as far as I can tell the kernel parts are ok ( journalling only screws up the r/w mounting )

Code:

grep hfs /proc/filesystems

        hfsplus

        hfs



cat /proc/partitions

I have tried different stuff and can't get it to mount.

Well found the problem it is a kernel problem but NOT a config problem see this:https://bugs.launchpad.net/ubuntu/+s...ux/+bug/734883

So I upgraded the kernel to 3.4.7 and it now load O.K.
Personally I think this sort of bug is pretty naff for linux, still at least its working now.
